Techtel, Australia’s leading broadcast systems integrator has commissioned a transmitter system for Digital Terrestrial TV in Papua New Guinea for a local service provider, enabling the delivery of more than 30 additional services for its subscribers in Port Moresby, over two newly added transport streams.
The DVB-T2 system itself incorporates power amplifiers based on LDMOS transistors technology characterized by high power density, allowing very high efficiency. Furthermore, it integrates a modulator that covers the main TV and Radio spectrums, equipped with the latest technology in signal processing allowing Digital TV signal broadcasting with the highest quality and reliability. The integrated transmitter is compatible with both single frequency (SFN) and multiple frequency (MFN) networks, a result of Egatel’s system’s configuration flexibility. In addition, the new DVB-T2 system features integrated digital adaptive pre-correction for easy commissioning and testing requirements; and flexible configurations accommodating various redundancy scenarios.
As a part of its integrated offering, Techtel supplied, installed, commissioned and tested a new 600Wrms (2+1) DVB-T2 transmitter system by Egatel, as well as seamlessly integrating the platform into Port Moresby’s existing transmission facilities by adding a new RF combiner with two narrow-band and one wide-band inputs. The combiner and its internal filters have been custom designed and fine-tuned to accommodate for four adjacent RF channels compliant with PNG RF spectrum allocations for broadcasting of DTV services. After comprehensive testing, Techtel’s integration team were able to achieve exceptional RF signal performance with shoulder value measured over 49dB, and MER value of higher than 35dB.
Mal Chandler, CEO of Techtel says: “We are proud to enable PNG’s largest service provider deliver a state of the art DVB-T2 Digital Terrestrial Television System resulting in the expansion of broadcast network coverage citywide. Egatel is continuing to demonstrate to the market that they are a reliable and trustworthy partner who together with Techtel will offer the region a better value option for many years to come.”
Techtel is an established provider of digital TV broadcasting transmitters with many other channels powered by Egatel in service in the Australian market.
